Oh, there's much smaller, believe me. Have you seen some of the "Terminals" on the Pacific or Indian Ocean Islands (Maldives Atoll), Rarotonga etc. I remember seeing a wooden hut for a "terminal" in Papua New Guinea.

And if you've been to Mombasa, Moi International (Kenya), you'll recall the check-in desks are situated in the car-park outside.!!

PS. Was that in France per chance? The flag does resemble the tricolore.

The terminal is small but, here in the Caribbean, most air terminals are small by international standards and some are the same size or smaller than the one in the picture. I really cannot identify the port though - could it be in the French Caribbean?
